Question Pcie4 nvme in a pcie3 slot

[WINTERLORD]

OK so I know if I use a samsung 990 or 980 pcie4 in a pcie3 slot I won't bennifit from the increased sustained r/w speeds but I'm wondering if I will bennifit from like the iops and other stuff that normaly slow down on a 970evo like random r/w or a high que depth and such?

Only difference is the controller on the ssd and how it handles data. Not at all something you would compare anyway because you'll not notice a difference between this or that model.

Apart from Direct Storage depending on game and adoption, main ssd benefits = random access. Random access performance is similar across all ssd types and interfaces. It's what matters in games.

Direct Storage will matter in near future.

Well I do more than games in crazy bout security so I routinely clean install windows handful a times a year as well as multitasking music ect I know bout direct storage but I wonder as this would be future proof to I wonder though since random access of a pcie3 like the 970 don't usualy hit 3kmbs maybe 1to2k and the iops are like 16k where as 990 is 750k so I know won't get all the performance boost or bennifit from sequential read/write but I wonder if random access and stuff that uses more iops if would he any real world bennifit given a pcie4 drive could prolly saturate the pcie3 bus with random ect
